WARREC partners with NCWSC to launch the first ever Bathymetric boat to assess sedimentation in Ruiru Dam

The Water Research and Resource Center (WARREC) in partnership with Nairobi City Water and Sewerage Company (NCWSC) has started the implementation of a reservoir sedimentation research in the Ruiru reservoir. The project entitled ‘Quantifying sedimentation rates and potential sources in Ruiru dam using Vibro-coring and field assessment techniques’ was launched on July 13th 2015, at the Ruiru dam site.

“I am pleased that today’s project launch, is putting into action, a project that has been planned with consultations between JKUAT and the NCWSC. This project is the first to make use of the state-of-the-art Bathymetric Boat, which, will use cutting-edge science to determine sedimentation of Ruiru dam” said Prof. Kahangi

In his sentiments during the launch, NCWSC Managing Director, Eng. Philip Gichuki appreciated the partnership with JKUAT in the research and called for more partnerships in implementing research and innovations. He also asserted that the research will assist in documenting about Ruiru dam.

“We need to run away from the rule of the thumb and ensure that decision making is based on facts.” said Eng. Gichuki. He also pointed out that involvement of all staff in research is key to enhance development.

WARREC Director, Prof. Bancy Mati in her speech pointed out that the short-term goal of the project was to assess the current reservoir sedimentation status and to determine conservation practices that will minimize watershed erosion and reservoir sedimentation. “In the long run, the project aims at establishing a center of excellence in reservoir and watershed management research and knowledge in Kenya and the Eastern Africa region” said prof. Mati. Prof. Mati further said, the equipment will be used to recover in-situ, cores of sediment from the reservoir bottom for laboratory analysis which will be instrumental in establishing the reservoir volume and its sedimentation status. “This is the first study of its kind in Kenya which utilizes the APS System” lauded prof. Mati.

She acknowledge Baylor University and USDA-ARS for donating the Bathymetric survey equipment, JKUAT , NCWSC, Government of Kenya (including MWI, MEWNR, AWSB, WRMA and other institutions) ,County Government of Kiambu… and all others for their great support for the project.
